Explanation:
Application Server is an expanded server role of Windows Server 2008 that simplifies the process of
deploying applications that respond to requests sent over the network from remote applications.
Windows Server 2008 provides support for applications by enhancing application availability and
accessibility through the Application Server role. The Application Server role provides environment

During the server role installation, administrators select services that support applications that are
designed to use COM+, Message Queuing, Web services, and distributed transactions. Microsoft
recommends installing the Application Server role when a custom business application is deployed
on the network and the developer has indicated that specific role services are required.

B is incorrect. The Network Policy and Access Services server role is a server role of
Windows Server 2008 R2. This server role offers various methods to provide users with local and
remote network connectivity, to connect network segments, and to permit network administrators
to centrally manage network access and client health policies. These methods use VPN servers, dialup servers, routers, and 802.11 protected WAP (wireless access point).

C is incorrect. The Active Directory Certificate Services server role is a server role of
Windows Server 2008 R2. This server role offers services to create and manage public key
certificates that are used in software security systems. These software security systems use public
key technologies to verify the identity of a person, device, or service, which can be used by secure
mail, secure wireless networks, VPNs, lPSec, EFS, smart card logon, and others.

A is incorrect. The Windows Server Virtualization server role is a server role of Windows
